Review on 📐 European Standard Extrusion 19-69 Inch by OUYZGIA by David Bott

Good strength and overall quality of these aluminum parts. The black anodizing looks nice and is reasonably scratch resistant. The T-slot pieces I have fit perfectly into the channels and the pieces are almost completely flat. They are just enough to be used for a frame or as an addition to a 3D printer or CNC machine. I have a pair of 2020 end caps that fit nicely into the holes on the ends. So overall dimensions seem good and I'm happy with this set of four 600mm pieces. Very well packaged and arrived in perfect condition.
